Linear Motion Guides for machine tools

LM Guides play a crucial role in achieving smooth motion, high rigidity, and accurate positioning in CNC machines and other applications.



Preload refers to the force applied to the linear guide's rolling elements (such as balls or rollers) to eliminate clearance and enhance rigidity.
The preload amount is typically expressed as a percentage of the dynamic load capacity.
Common preload levels for linear guides are 2%, 5%, or 8% of the dynamic load capacity.
For example, if a linear guide has a dynamic load capacity of 25,000 N and 2% preload, the preload force would be 500 N².

Precision and Sizes
LM guides achieve high precision, rigidity, and long service life.
They come in various sizes, allowing for compact machine designs.
The LM Guide's circular-arc groove design enables it to bear both vertical and horizontal loads.
Sizes vary based on load requirements, ranging from smaller guides to larger ones for heavy-duty applications.
LM Guides are available in different accuracy classes, such as H (high), N (normal), and P (precision), depending on the application requirements¹⁴.
